Inventor: SHIMIZU AKIHIRO
IPC: H01L21/8238
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To improve large-current driving capacity for a desired substrate effect, by providing a first semiconductor region of a conductive type reversal to that of a semiconductor region so as to surround a channel region side, and also providing a second semiconductor region of a conductive type reversal to the semiconductor region at such position of a semiconductor device as specified depth, for suppressed short-channel effect.

Abstract: PURPOSE: To reduce the gap between a magnet and the connected parts of a commutator plate and armature coils, by making the surface of the commutator plate lower than that of each armature coil which is almost elliptically formed by winding  a copper wire around an iron wire coil plate.   
     CONSTITUTION: An iron wire coated with an electric insulating film is wound to manufacture a slender elliptic iron wire coil plate 1. A copper wire is wound around the coil plate 1 to manufacture an elliptic armature coil. A commutator plate 3 is set in the center of a disc-shaped recess of a metal mold so that the surface of the commutator plate 3 is by 1mm lower than that of the armature coil. The armature coil and the commutator are connected to each other along the recess so that a soldered face 7 is located below the surface of the armature coil. A plurality of such armature coils are sequentially provided around the commutator plate. A synthetic resin 6 is injected into the metal mold so that the commutator plate and the armature coils are integrated with each other as a disc. A shaft 5 is provided through the center of the disc. As a result, the connected parts of the commutator plate and the armature coils are located at a small distance from a magnet 11 and the efficiency of a motor is raised.

IPC: H05K1/02
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To check breakage of a guard pattern by providing a guard pattern surrounding a signal pattern and an overlap guard pattern, respectively to a plurality of guard pads for checking continuity, and checking the guard pattern between the guard pads. SOLUTION: At one of guard pads 20 and 21, a signal pattern 30 is surrounded by a guard pattern 11. At the other guard pad, an overlap portion 52 is formed with overlap guard patterns 50 and 51 overlap with each other. As the guard pattern 11 at one of the guard pads 20 and 21 is open looped, the continuity of the guard pattern 11 can be checked by pressing a probe between the guard pads 20 and 21. Accordingly, the breakage of pattern can be easily checked only by continuity check between the guard pads before parts are mounted on the printed circuit board.

Filed: 1990-06-22
Abstract: PURPOSE:To miniaturize this device by inserting a cartridge in the state of exposing a part to the outside, and processing the information of an optical disk in such a state. CONSTITUTION:The head part of an optical disk cartridge 3 is opposed to an inserting port 2 in the main body 1 of the device, and the cartridge 3 is pushed into the inserting port 2.

Title: Generating method for video signal
Inventor: DEBITSUDO JIYON HEDORII
IPC: H04N5/262
Filed: 1991-07-03
Abstract: PURPOSE:To prevent deterioration in a composite video image at cross point of plural input video images by using only one DME generator. CONSTITUTION:A DME generator 1 uses an operation device 3 to receive an input digital video signal and a key processing unit 10 uses control information sent by a control unit 2 to calculate a key signal KV and the signal is fed to a mixer 7. Moreover, the mixer 7 receives an intermediate background signal and the mixer controls the insertion (keying) of the video signal to the background signal via the operation device 3 by using the signal KV. The signal processing is implemented sequentially stepwise and the key value signal KV is generated for each picture element for each field of each stage. The signal KV is used for cutting (elimination of a face to be hidden) and for decreasing aliasing (indention) of an end ridge of crossing between a picture to be operated represented by a signal subject to prescribed anti-aliasing processing and a picture represented by other processing signal. Thus, deterioration in a composite video image outputted from the DME 1 is prevented.
